I hope I'm not at all stepping on the developer's toes by pointing out you can fullscreen it by going to the iframe's source, where you can also have some fun trying to script it.

I'm in the early stages of designing a junior high programming curriculum and think this may be a great example of an engaging, practical experiment.

  boost = function(duration, interval){
      setTimeout(function(){
          clearInterval(window.kp)
      }, duration)
      window.kp = setInterval(function(){
          $(document).keydown()
      }, interval)
  }

I know I enjoyed playing with that snippet! Thanks for sharing.
